So, obviously, you can try ANY vegetable dish, but I'm going to list a a few MAIN dishes to get started. You can add any tvp (textured soy product) or Soyrizo (meatless soy chorizo) to any or all of these. Since I'm not much into "Exactness", some of these are pretty general to taste and to the size of your family/guests.

Chili

1 can of diced tomatoes (or do it fresh!)
2 cups Pinto Beans
1 cup Red Kidney Beans
1 chopped onion (I put a little more)
8 chopped cloves of garlic
Chili powder, Cumin, Seasoning Salt, Oregano (or anything that suits your tastebuds)
Vegetables - any you desire such as, mushrooms, corn, celery, green bell peppers, red bell peppers, etc.

Put beans in slow cooker covered in water and cook until tender. Drain 1/2 and add other ingredients. Cook a couple of hours.

Add Sour Cream and Cheddar Cheese (vegan if you have or can get it!) and add some Multigrain Mini Crackers for crunch and texture! The kids ate the whole crock pot and kept asking for more!
